UNITED NATIONS (Reuters) - Britain circulated a U.N. Security Council draft on Thursday that would urge all nations to ban incitement of terrorist acts in hopes the measure would be approved during the forthcoming U.N. world summit.

The draft follows Britain's controversial domestic crackdown on incitement, announced by British Prime Minister Tony Blair on Aug 5, in response to bombings that killed 52 people in London in July.

Adoption is aimed at a Security Council meeting during the summit from September 14-16. The session would be attended by world leaders with seats on the 15-member council, including Presidents Jacques Chirac of France, Vladimir Putin of Russia and Luiz Inacio Lula da Silva of Brazil...

The draft calls on nations to "prohibit by law the incitement of a terrorist act or acts through the adoption of such measures as may be necessary and appropriate and in accordance with their obligations under international law."

It says all countries should take appropriate measures to counter "violent extremist ideologies, including steps to prevent the subversion of educational, cultural, and religious institutions by terrorists and their supporters."

The measure also says nations should deny refuge to people with "serious reasons for considering that they have been guilty of such conduct" and see they are brought to justice....

"But without a clear definition of incitement -- and it is lacking in this draft -- states could be encouraged to define incitement in overly broad terms and, for example, pass laws to prohibit legitimate articulation of opinion, such as expressing general support for a rebel group," Dicker said...

"Islamophobia" in parts of the world is fuelling terrorism, the head of the United Nations said on a visit to Saudi Arabia Sunday, as anti-immigrant sentiment rises in some countries.UN Secretary-General Antonio Guterres made the comment to reporters after talks with Saudi King Salman, Crown Prince and interior minister Mohammed bin Nayef, and Deputy Crown Prince Mohammed bin Salman."One of the things that fuel terrorism is the expression in some parts of the world of Islamophobic feelings and Islamophobic policies and Islamophobic hate speeches," Guterres said at a joint news conference with Saudi foreign minister Adel al-Jubeir.

"This is sometimes the best support that Daesh can have to make its own propaganda," Guterres said, using an Arabic acronym for the Islamic State group of Sunni extremists in Syria and Iraq.The terrorist group has also claimed deadly attacks in Saudi Arabia and in Europe.Anti-immigration politicians including France's Marine Le Pen have seen their popularity rise after an influx to Europe of migrants, many of them Muslims fleeing wars in Syria and elsewhere.President Donald Trump has also been a critic of what he sees as lax immigration policies in the U.S., issuing a travel ban blocking travelers from Iran, Iraq, Libya, Somalia, Sudan, Syria and Yemen for 90 days. That order is currently being challenged in federal court.Syria's conflict has created 4.8 million refugees and killed more than 310,000 people since it began with anti-government protests in March 2011.Guterres said "we will never be successful in fighting terrorism in Syria if an inclusive political solution is not found for the Syrian people."A new round of UN-sponsored peace talks is scheduled for February 20 in Geneva.
